Windows 7 resolution and DPI on Retina MBP

I just ordered Retina MBP. This is my first Mac OS X.


I haven't seen by myself running Windows 7 on Retina MBP, although I didn't check at Apple Store.


But, I saw a review on YouTube:

It shows that Windows 7 on Retina MBP can freely switch to lower resolutions rather than tweaking DPI settings.


I personally hate to change DPI settings other than 100% setting because many programs and fonts are ugly.


I know that by default 150% or 200% DPI is set for Windows.



Here is my questions:


(1) Is it possible to set 1440x900 (divided by exactly 2) resolution with 100% DPI (96 dots per inch)?


(2) If not, what it looks like if I set 1680x1050 with 100% DPI? Is this readable? Of course, I assume this setting would be possible.



-thanks

I've not heard of any display issues with a MBP-R running Windows 7. And, yes, you can set the res in Windows to your liking. I'm sure I would have read if anyone had been having problems as I monitor this forum frequently. I did run across on post in when the poster said that he/she was running OSX under Lion at 1680 x 1050 and was "am happy as a clam."


I don't think you'll be disappointed - perhaps someone running Windows 7 on a MBP-R will chime in here but, as far as I know, there are no problems with screen res.


Good luck,

All settings but the native setting (2880x1800) will look very blurry. If you set the DPI to 200%, then some programs which have been written in such a way that doesn't take DPI scaling into account will look quite funny. A very common example is Firefox.


If you set the resolution to 1440x900 (which is exactly 1/2 the resolution of 2880x1800), you will still get blurry text like other resolutions.


The bluriness isn't necessarily bad. You can imagine this basically as 2x Supersampling Antialiasing applied to the whole image.


The reason for this is because the hardware which scales the image applies a bilinear filter even if your resolution is an exact integer multiple of the native resolution (which it doesn't need to and shouldn't). This will likely require a firmware update from Nvidia to fix (which is unlikely, they have known about this problem for quite some time now - 30 inch monitors have a native resolution of 2560x1600 and the half resolution 1280x800 has the same problem).

Correct. If you use 1440x900 in Windows, it will be blurry.


There is no reason to set 1440x900 in OS X. Just use "Retina Mode". Almost all non-games in Mac OS X are already properly written to take advantage of "Retina" resolution.


If somehow in Windows all your programs were DPI-scaling aware. You could set 200% and 2880x1800 and achieve the same result as "Retina" in OS X.


If you are interested, read this Anandtech article on how Mac OS X does scaling: http://www.anandtech.com/show/5996/how-the-retina-display-macbook-pro-handles-sc aling.


The downside of the way that OS X does scrolling is that it is VERY choppy compared to Windows because OS X does it on the CPU. When Mountain Lion hits, supposedly some of the animation will be done on the GPU to make it a bit smoother, but don't expect it to be anywhere near as smooth as it is in Windows.
